I have 4 Asus Geforce GTX 670s SLI liquid cooled (don't worry mine surpasses the Zotac and Gigabyte, and I get the beast ROG interface) and that means its taking every space on my Rampage IV Extreme/BATTLEFIELD 3 motherboard. My case has 10 PCI extension slots so I can have 2 more cards if I could reach the other 2 slots. I only need to get a sound card around there. Are there any extenders that will clear the bottom of GPU1, over GPU2-4 clearing the tubes (can be moved) and SLI bridges (shouldn't be a problem), down before extension slot 9(or 10, maybe 1 or 2 depending on where the MB fits) and in line with an extension slot. I can't find any good extension cards, I don't even know if that's what I'm looking for. And I need a brand name or a good provider (couldn't find any). I don't even know if they exist. If nothing will work then I'll be fine without it. Also what about a extra PCIe slot that plugs in externally mounted internally or one that plugs into SATA or molex, if it plugs into anything like that, that would be amazing because I have PSU plugs for days and there's no short on my MB.
